How about the design corps training course?

No, 5500 is a bit worthless and a bit misleading. The teachers are all from training courses that have only been engaged in 3D software for one year or less. They have no experience in exhibition design at all. They lecture every day. The knowledge is very little, it takes a long time, and there are no handouts. If you really want to learn design well, I personally recommend learning from the designers of exhibition companies. Nowadays, many exhibition companies also provide design training, and the tuition is cheap.
